How do I make a door with a randomly generated code?

I have been going slightly crazy trying to make this work.

Goal:

I have made this script that is supposed to create a random code. Then, if a player types that code in chat, the door gets destroyed

Problem:

This code won't do anything. It doesn't give me an error message and there is no script errors according to Roblox studio. I have tried to use a bunch of other chat door scripts as well, but I came to the same problem.

Here's a cut version of my script (Cut out the parts that aren't giving me problems)

local code = math.random(100000,999999)

game.Players.PlayerAdded:Connect(function(p)
	p.Chatted:Connect(function(message)
		if message == code then
			game.Workspace.Secret.SecretDoor:Destroy()
		end
	end)
end)

print(code)

Note: This script works if line 5 has quotations around it, but if I did "code" then it would be looking for the word code, not the local code.

Thank you for reading, hope I can find a solution to this infuriatingly small script I've been working on for 2 days :)
